Groundwater Speed Dating! Can you find a match?

Post by Matt Herod Welcome to the first edition of groundwater speed dating. In today’s post I introduce you to a motley crew of isotopes and chemicals that hydrogeologists and geochemists use to date the age of groundwater. After meeting all of the contestants it will be up to you to pick your favourite and perhaps propose a second date. On your groundwater samples that is. Before I introdu ...[Read More]

Monitoring groundwater drought without measuring it

Monitoring groundwater drought without measuring it

Post by Anne van Loon, University of Birmingham You might remember that the summer of 2015 was extremely dry in large parts of Europe (Figure 1), leading to crop losses, wildfires, drinking water supply deficiencies, and reductions in energy production and navigation (Van Lanen et al., 2016), whether you experienced it yourself or read about it in the newspapers. Based on incomplete information th ...[Read More]

Global fossil groundwater resources—the grandkids like hanging out with the grandparents!!!

Post by Scott Jasechko, University of Calgary Groundwater is the world’s largest family of fresh and unfrozen water, and its members range from young to old. There are toddler groundwaters recharged more recently than the year ~1960. Our earlier research showed that these modern groundwaters make up only a small share of global groundwater stocks (Ref. 1 and Water Canada). But what of ancient ‘fos ...[Read More]

Musical groundwater?

Musical groundwater?

Post by Kevin Befus, University of Wyoming I don’t mean to get your hopes up, but keep them up there. I’m not talking about recording the sonorific excitement that is groundwater flow. And, I’m not talking about the squeak of a pump handle, the gurgling of a spring, the grumble of a generator, or the roar of a drill rig. Rather, I want to share with you some songs that reference groundwater in one ...[Read More]

Of Karst! – short episodes about karst

Episode 1 – A different introduction to karst by Andreas Hartmann,  Lecturer in Hydrology at the University of Freiburg Usually, textbooks or lectures start with the theoretical background and basic knowledge of the topic they try to cover. Writing my first contribution to the Water Underground blog I want to take advantage of this less formal environment. I will introduce karst as I and many othe ...[Read More]

We’d like to bring your attention to two new publications, relevant to the theme of this blog. These publications share some common themes, including emphasising the significant role for geoscientists in sustainable development, and enhancing the skills training of geoscientists to support effective and positive engagement. For further information on either of these articles, please contact ...[Read More]

What is the volume (in kegs) of groundwater is stored on earth?

What is the volume (in kegs) of groundwater is stored on earth?

Last week I gave a ‘blue drinks’  presentation for a networking evening for the Victoria chapter of the Canadian Water Resources Association entitled “How much groundwater is on earth?” based on our paper from Nature Geoscience last year. Since the night was hosted at Philips Brewery, an awesome local brewery (who makes Blue Buck, the perfect blue drink, and lots of other g ...[Read More]

Emerging Contaminants: The Rough Teenagers

Emerging Contaminants: The Rough Teenagers

In geochemistry I see the term “bad actors” used more often than it should be to describe well-known environmental contaminants. “Bad actors” refers to contaminants we see frequently in the environment and know have significant environmental or human health effects. Think mercury, nitrates, lead, arsenic, sulphur dioxide, etc. However, this article is on the up and coming c ...[Read More]
